There comes a time where there is a need for entropy in a script. Recently I needed to run a script on ~120 servers. I was logged in via cssh so all of my keystrokes play out on each server at the same time. I could execute the script on every server, but because the script made internal web connections, having them all execute at the same time could have been harmful as it could have flooded one of my main servers. Here is my solution:
Here is the last piece of the series: The Queen. Done the same method as all of the other cylindrical pieces with some detailing of the crown. Here is my initial blender mock up:
Now that the CNC Lathe is completed, Producing the other pieces will be much easier. So I am ready to introduce the bishop. This is the initial design done up in Blender, minus the slice in the head which will be done manually on the milling machine. Stay tuned....
Here is the initial design for the king in Blender. Before I've shown you the 3-D mock up of each piece but this is really how the piece gets created. I've created the king with the same method as all of the other pieces
with one exception. The king has a cross on top of his head that is flat
on two sides.
To begin with the pawn, I've started the same as the Knight. I used blender to create a basic shape, and then refined the look and feel. I need to make sixteen of these exactly the same. My skill at a manual lathe is not that great. I could probably create one, but duplicating that effort would be an exercise in frustration. To I've decided to convert my old manual hobby lathe into a CNC (Computer Numeric Controlled) lathe. this way I take the design from the computer and have it turn the pieces out on the lathe. Is it cheating? Well, maybe. But I'm all about technology and having tech do the work for me. So off to convert the lathe....
Can be used as a drop-in replacement for cron.
Can execute jobs based on event triggers.
Secure communications between master servers and clients.
Clusterable: Master can automatically fail over so any number of secondary masters.
Ajax web interface for better monitoring and execution feedback.
Graphing/Reporting: Visualize the running duration and timing of your jobs.
This blog will document my project, creating a machined aluminium chess set from scratch. These pages will be updated as the project progresses so check back periodically.
All designs are my own and the materials used were mainly scrap (soda cans, hard drives, etc)
What would you do if your car's battery is dead and you don't have anybody around to give you a jump? Need to have it working in time for the morning commute? This is what I did when I was in this situation. This is a quick tutorial on how to charge you car's battery using a power supply from a PC.
It's handy to have some raw materials to throw at the Lathe and Milling machines for quick parts and projects. I needed some basic aluminum round stock for turning small parts and I had a collection of soda cans and small garbage bits that were perfect for the job...
